According to Jon Aars, male polar bears sometimes hunt adult walrus.

And what a video it is, killed a much larger bull walrus using just brute strength and his strong neck muscles to move it. When I truly looked closely at the Walrus in that 1st video and then compare it to the video just above this post, the first video of the Bear dragging the Walrus onto the ice does NOT appear to be a fully grown adult bull. Too small.... However, still not an easy task. |

Anyways, looked at least 2000 lbs to me, very impressive for the polar yeah. |

Polar Bear vs Walrus While polar bear (Ursus maritimus) is a land-based marine mammal the walrus (Odobenus rosmarus) is a flippered aquatic mammal. The walrus is recognized by its prominent tusks like elephants’. White bears are the predators of walruses. However walrus is a big animal and only adult bears can afford to take down such a large prey. Sometimes young polar bears also get killed by the walrus. Polar Bear vs Walrus Adult walruses typically measure 2,000 kg (4,400 lb) in weight whereas male polar bears can weigh as much as 350 – 700 kilograms. The weight of the heaviest polar bear is reported at 1,000 kg. Clearly there is a significant difference in sizes of both marine animals. The biggest walrus is twice the size of the biggest polar bear. Despite the size difference polar bear preys on walrus and not the other way round. Where Do Polar Bears and Walruses Live? Polar bears and the walrus live in the Northern Hemisphere. They both have occupied much of the arctic including Atlantic Ocean. Polar Bear vs Walrus Hunting While polar bears have long been the victim by the indigenous people walrus isn’t safe either. Indigenous people kill walrus not only for its unique tusks but also for skin, meat, bone, and fat. In the 19th and 20th century people used walrus ivory and blubber to serve numerous purposes. Polar Bear vs Walrus Diet Unlike polar bears walruses have quite diverse diet. Walrus is thought to consume 60 genera of aquatic animals. Walrus eats shrimps, crabs, sea cucumbers, mollusks and many others. Both polar bears and walruses prey on ringed seals. Polar Bear vs Walrus Life history Walrus and polar bear seem to have a similar lifespan. Polar bears live around 15 – 25 years and walrus’ lifespan ranges from 20 – 30 years. Walrus attains the sexual maturity at 15 years age whereas polar bears become mature as early as in 4 – 5 years. Female polar bears and female walruses are called sow. Polar bear cub weighs only one kilogram at birth as against the walrus cub that weighs as much as 45 to 75 kg. While polar bears live alone, walrus breeds in colonies of tens of thousands of individuals. Population The overall global population of walrus is estimated at 200,000. Polar bears have a total population of about 25,000. Predators Polar bears have no natural predator in the arctic. Walrus has two potential predators; one is polar bear and the other is a killer whale. polarbearfacts.net/polar-bear-vs-walrus/amp/ |

You might post your opinion on any animal vs animal in story mode but please make it reasonable according to the rules set by brovear. I will post mine:
Polar bear vs walrus:
Back in the days beore the human intervention and before the global warming which has drastically destroyed the polar bear habitat and decreased their size by 15%, polar bears remain unchallenged. During that time polar bears did reach their huge sizes that others discussed about in the animal forums - though those huge specimens are mostly history now - a huge male polar bear weighing 1800 pounds rulled the ice unchallenged. He was the apex predator in his region and fears none but the orca which could make even the largest land predator look like a puppy. Now polar bears seldom prey on adult walrus despite being capable of killing them for certain reasons. Firstly, even though an adult male polar bear is capable of taking on the biggest bull walrus, walruses are often found in herds and he cannot kill an adult walrus quickly enough ( thanks to the four inch thick skin which would prevent a polar bear from easily piercing its vital organs or jagular vains) before the intervention from other adults or before the adult walrus reaches water in which the tides will shift to the walrus. However, this polar bear is on the hunt once again after not eating for a week.
Nearby there was a walrus herd resting on a hill where there were female walruses resting nearby the sea with calves with the adult males resting further away. this would give the females and babies easier access to safety should a polar bear approach.
[Image: smpolar23.jpg]
The polar bear was about to appoach the herd but then something change his direction when he smelled the smell of the fresh carcase of a humpback whale which had been stranded on the shore and esentially been dead for a few days. The polar bear to his delight moved towards the carcase but to his suprise he saw an old bull walrus weighing 4400 pounds eating away at the carcase ( once in a while old bull male walruses turn carnivorous killing seals and eating dead whales and this was certainly one exception). The polar bear crept up to the walrus and pounced on his back ( hoping to secure two meals) and bit into its neck, the bull walrus struggled but could not shake the attacking bear off. However, with the walrus skin being so thick the polar bear could not find a way to pierce the jagular vain or other vital organs despite having a firm hold on the walrus with his teeth and claws. The walrus knew his only means of escape would be to move towards the water ( the story ends here if the polar bear foolishly held on and got stab to death by the walrus in the sea) and by the time the polar wisely let go and returned to the whale carcase feasting away with his opponent/prey gone temporarily. The walrus escape death but sustain some cuts and bite marks which left him bleeding and angry he had been disturbed by a bear from his meal. The walrus slowly returned to the carcase and seeing the bear at the top most of the whale carcase eating away - oblivious to the surrounding - the walrus climb up the whale carcase with the intention of taking revenge on the bear. The walrus crept up slowly toward the unsuspecting bear and raised its tusk about to stab whe bear - fortunately the bear sensing danger managed to turn around a swipe a paw blow at the walrus head just as the walrus miss his mark and sent his tusk into the whale carcase instead. The polar bear knew that to kill the walrus, he would have to change techniques and gave the approaching angry walrus another blow to the head which this time send the walrus in shock for a while. The polar bear than pushed the walrus off the sliperry whale carcase to the othe side of the whale carcase( further away from water this time) which resulted with the walrus unfortunately breaking one of his tusk ( well - the polar bear may have already unknowingly hit his tusk while attacking his head) immediately to be pounced on by the polar bear once again. This time instead of just biting the polar bear did use a bit more paw swiping to the head to stun the walrus further. The walrus knowing it was relatively vulnerable headed back to the sea again hoping to escape this time but the polar bear did not let go and every now and then would swipe the walrus on the skull hoping to slow it down and this time bit its head which eventually caused the walrus too finally die near the sea which left the polar bear two meals to feast on ( a walrus and a whale carcase) .

While orcas are more powerful than walruses, the former is not a prey for a polar bear but if we are to exclude the subject called prey, the orca is the most dangerous animal to even the largest male polar bear (even more dangerous than a walrus is). |

I have no idea what you got blended into your last post OldFossil, but it can't be Quoted.
Last I checked, we have no official record of an Orca ever killing a polar bear. Jacques-Yves Cousteau once witnessed an Orca attack a bull walrus. He told of a long bloody battle. It appeared that the Orca killed the walrus in the end, but he also stated that quite possibly the Orca would not survive the wounds inflicted by the walrus.

Brobear, I am not sure either as I use only my lap top or mobile phone to post. Orcas consider walrus their prey rather than polar bears probably because seals are their favourite food and the walrus is a member of the seal family. Regarding an orca not surviving wounds inflicted by a walrus, I find it hard to believe as bull walruses fight each other yet death is rare song them due to thick hide and blubber. Now the orca is larger and has thicker skin and blubber than any bull walrus.

If he said it; I believe it. |

The walrus must be an old carnivorous bull since its a one on one fight. Regarding the orca, I believe its also a bull as it is solitary and alone but what was the condition of the orca?

I didn't witness the fight. An orca attacked a bull walrus ( shell-fish eater ) and the walrus defended himself. The walrus managed to deliver some possibly lethal wounds with his long ivory tusks, before the orca killed him. Cousteau was amazed at the fierce fight the walrus gave to the orca.

I don't doubt the orca suffered wounds as the walrus have tusks that can break nine inch of ice. However, Jacques-Yves Cousteau didn't say the orca died but there is a possibility it might have. Once again death among walrus fights are rare as said in documentaries.

This is a great account mate. Polar bear observed killing a large adult male walrus. The study area was the Central Canadian high artic, this means the Atlantic walrus, (Odobenus rosmarus rosmarus), which weights up to about 3300 lbs and has shorter tusks than the Pacific walrus, (Odobenus rosmarus divergens), which weights up to 4400 lbs and has longer tusks.
So, we most likely have a 1500 lb polar bear that killed a (around) 3300 lb walrus, this is IF that walrus was at its max weight. That subspecies averages around 2000 lbs though. The reason i think that walrus weighted closer to the max weight of around 3300 lbs than to the average weight of 2000 lbs is because the description was a "large adult male walrus".
nammco.no/topics/atlantic-walrus/
The walrus weighted more than double the polar bear itself. (This is all my own speculations based on the max weight of those 2 animals, as the actual weights of the animals were not stated. The weights can be a little more or a little less, but i would think only the largest polar bears would be able to kill a large adult male walrus). An incredible accomplishment.

I think you're right in that it would take a large male Polar Bear to kill an adult male Walrus. Even then, a very risky decision for a single Bear.
